-General stmcture machine.

As seen clearly in Figure 1 of the drawings, the machine of this invention may be said to comprise an adding section A and a counting section B, the counting devices being located at the. front of the latter section and consisting of a number of individual counters or registers suitably arranged beneath a casing plate C apertured at intervals so that the numbers of the counting wheels of said devices may be seen during and after the operation of the same. The adding section A of the machine for all practical purposes a complete adding machine of itself, being constructed substantially in accordance with the adding niachine embodied in the copending application of Nelson Whit-e, Serial Number 755.817, filed March 20, 1913, reference being made to said application for details of said. machine which will not be fully presented hereinafter, being non-essential to the peculiar novelty of the present invention;

The adding section.

As is usual, the adding machine forming the adding section of this combined machine includes a keyboard having a plurality of rows ofkeys 29, each row preferably nine in number and the capacity of the machine susceptible of change merely by using a larger or smaller number of rows of keys and corresponding cooperative parts. As seen in Figure 3, each key 29 of a row is formed with'an inclined slot receiving a stud 92 of an indexing plate 90, the several plates 90 for each row of keys 2! being superposed and supported by any conventional means tp slide longitudinally and horizontally to and fro so that by the depression otany one of the keys 25) its as sociated plate 9.0 will be. projected at the front end into the path of movement of a projection 80 of the adding rack 80, one of which is provided for each row. Theplates eer/goes 9%) differentially limit the movement of the adding rack 80 with which they cooperate, allowing from one to nine increments of movement for said rack for setting up predetermined amonntsby the adding wheels 87 included in the accumulating mechanism at the front of the adding section A. The teeth of the adding rack 80 are of course adapted to engage and be disengaged from the pinions 84; of the adding wheels. as controlled by the ordinary operation of the machine,-and totalizing means disclosed fully in the application hereinreferred to. The excursions of the adding racks 80 control the movement of the type carriers !)5,in the well known manner. levers 75 being connectedv at their front ends with the adding racks 80 and at their rear ends with said type carriers 95. A main actuator including the handle 38 (see Figures 1 and and the shaft 39, is provided and is operable to raise the cam slotted arms 69 and the transverse detent members 73 and 74 carried by the latter. thereby releasing the levers 75 from the detaining action of the part 74 and permitting certain springs 76- to actuate the levers 75 so that predetermined adding racks will move downwards, and the type carriers will be elevated so that their type are brought to the printing point under the control of the indexing plates 90. At a suitable period in the operation of the main actuator handle 38 the hammers 171 will be tired, causing the amount set up by the depression of the keys 29 to be recorded usual, the said amount being accumulated by the adding wheels in the customary manner.

The counting section. (Selectors anal actuatom.)

In the counting section of the machine are mounted a number of series of horizontal selectors 20 (see Figures 3, 4 and there being one series of selectors for each set of keys disposed transversely of the keyboard or longitudinally of the whole machine. The selectors are downwardly dcpressible. being normally npraised. by springs 26 connected thereto intermediate their ends, and said selectors extend into the keyboard or adding section of the machine beneath the lower ends of the keys oi. the latter and have projections directly ongagcablc by said keys when depressed. Thus it is that each key 29 is adapted to engage and depress one or several of the sclectors 20 whereby to cause hooks 48 on the right hand ends of said selectors to be engageablc by a bail 47 mounted upon a rock shaft 46 near the right hand end of the machine. tion of the handle 38 owing to the provision oi a cam movable with the shaft 5-39 (see Figure 5), saidcam engaging a roller -31 of a lever l2. pivotally supported inter- The shaft, 46 is rocked on each filnl'tifi to be 110W described.

it is contemplated. to u I 20 to select for operation the actuators oi the counting devices at the front portion of the counting section B otEthe machine. The

said actuators consist of longitudinally slidable bars (see Figures" 1 and 4) each bar said end may he interlocked with en udja-J' cent arm ll of the counter actuating shaft 12. Any suitable means may he provided intermediate the selectors 20- :ind the counter actuators 3 whereby each selector ls adapted to actuate or set one or more of the actuators 3 into positions in niiich they are connected with the cooperative erzns llend thus rendcred opershle to cause corresponding operation of the counting deviceassociated with each predeter nined actuator The preferred means foresaid comprises projections Ll on the sol ctors 20 adapted to and swing boils 22, pivoted at 22, said bails halving lever arms 22- hngoging tit their lower ends with members 3Wheroby to shift the actuators 3 into and out of interlocking relution with respect, to their urnis 11.

The disk Qll carries at one side thereof the puwls 21st pressed outwardly by spring means as art 215, said pawls en- ;iaging' with teeth 216 formed internally on It is to he understood 211 and the counting wheels are coaxially mounted loose on the resetting shaft 212 and there is provided between each counting wheel 213 and its next adjacent counting wheel 1. suitable carryover mechanism such as illustrated in Figure 12. This transfer mechanism is substantially the some as that of United StatesPatent No. 798,502

issued May/19, 1908), to W. L. Sandage and no claim istherefore inade to the mechanism as slmwn/therein. As seen in Figure 12, however; the units wheel 213 has pivoted thereto a, transfer pawl 213' which when the nose thereof engages a projection 217 and the tail the *eof is received in a recess 218, interlocks the units wheel 213 with the tens wheel 213 at its side, the tens wheel having pro jections or teeth ZlQ-Zin'its inner periphery adapted to be engaged by the pawl 213 when so adjusted. The projection 217 is in the nature of a. cum, beinglormed on a collar i220 keyed or otherwise fixed on the resetting shaft 212. Obviously at one time during each revolution ,'of the units wheel 213, the pawl 213 thereof, which ishoused in the recessed side of the tens wheel, is cuused to move outwards at. its nose into engagement with the teeth 218 of the ivheel 212 of higher denomination, whereupon the increment of movement imparted to the units wheel or wheel of lower denomination at this time is likewise imparted to tho wheel of higher denomination because the two are temporarily interlocked din-hug one-tenth portion of their revolution, in'un obvious manner. When this increment of movement happening at the time of transfer, is" ended. the tail of the pawl 213" rides out of tho.

.rcccss 218 and disengu ies the pawl of the counting Wheel of lower Xlenomination from the-wheel of higherdenomination in nu oh vious manner. The specific mode ol? llunsfor or carryover above described is inumh lcrial tothis invention because it is contemplated to use any desirable type of arryovcr for the co ntino wheels of each counting device. the wheels of all of said devices being carried by the common shaft 212, the latter forming not-only the axis for the counting wheels but also a resetting means.

Every time one of the actuators 3 is operated its outer ehd engages the slide 208, thereby moving the latter outwards against the tension of a spring 219. At the same time the connection of the slide 208 with the disk 211 partly rotates the latter and such movement is correspondingly imparted to the units wheel of the counting device, the movement being transferred to the Wheels of higher dcnominathms in the customary manner above explained.

Counter resetting mechanism.

As clearly shown by Figure'ti of the drawings, the counting wheels of all of the counting devices carried by the plate 201 are mounted. upon the common resetting shaft 212. Each counting device comprises as its main parts the counting Wheels 213 referred to, the disk 211 for each setof wheels and the spring retracted slide 208 interlocked with said disk. Assuming that the manipulative keys 29 have been operated through a series of transactions ofthe machine and it is desired to normalize the various counting devices, the operator will depress the finger piece 220 of a locking lever 22]. which is mounted on a locking shaft 222 and formed with a lug 223 adapted to engage in a notch 221 formed in the locking wheel 225 rigidly secured to the shaft 212. The depression of said lever 221 which is normally held bya spring 226 in locking engagement with the wheel 225, does two things. First the shaft 222 is rocked with the lever as the ln 223 is disengaged from the notch 224, and the wheel 225 and the shaft 212 are released and free to rotate in the brackets 22? supported by said shaft on the plate 201. The shaft 222 not only carries the locking lever 221 at one end but at the other end an arm 228 is mounted, the said arm 228 and the le ver 221 having inwardly extending studs 229 projecting beneath a resetting member or plate 230. The resetting member or plate 230 extends lengthwise of the main supportr ing plate 201 and is formed with a flange 230 adapted to engage with resetting lugs 231 one of which is provided on the peripheral portion of each counting wheel. In other Words, under normal conditions there is hung on the shaft 222 a resetting plate having a spring 232 connected therewith and with the locking lever 221 (see Figure 8), sair "pring tending to move the flange 230 of the resetting plate in engagement with the resetting or zeroizing lugs 231 of the counting Wheels. However, normally the spring 226 connected-With the lever 221 is of greater tension than the spring 232 and thus when the lever 221 interlocks Witlrthe locking Wheel 225, the pins 229 carried by the lever 221 and by the arm 228, bear against the under side of the resetting plate and hold the latter in a position in whiclnit cannot menace engage with the zeroizing lugs 231. The depression of the locking lever 221., however, moves said lever to disengage it from the locking wheel 225 and simultaneously the she ft. 222 is rocked to permit or very slight downward movement of the resetting plate 230 and its flange 230' so that the flange in the path olirotation of the lugs 231 and when the resetting shaft 212 is turned by the knurled knob or handle 233, the various counting wheels of the several counting devices will be Zeroized owing to the engagement of the lugs 231 with the flange of the resetting plate 230. At this particular time the notch 221- will be again opposite the locle ing lug 222 and the latter will spring into the notch under the action of the spring 226 normalizing the locking lever 221, locking the shaft 212, and rocking the shaft 212 suf liciently to cause the pins 229 of the parts and 225) to raise the resetting plate into a position wherein its flange 230 is out of the path of rotation of the lugs 231.

Main accurate) connection to counter oc fuab my shaft.

As seen in Figures 13 and 1 1, the actuating shaft 12 which carries the arms 11 capable of being interlocked with the actuators 3, is provided with an arm 68 having a hook (ll engaging normally a. stud 66 on the vertical rocker arm 56. The rocker arm 56 is carried by a' shaft 55 which also has a for- Wardly extending arm 54 bifurcated at its front end 5 1' so as to engage a stud on an angular lever 19 which is mounted on the main actuating or handle shaft 39, a spring 50 tending to pull the rear arm of the lever 19 downwards. Having in view the lore going it will he apparent thatas the handle 38 is pulled forwards the shaft 39 and lever 49 are rocked, pulling the arm 56 rcarwards. ment of the arm 56 is communicated through the hook 64 to the arm (53 and to the shaft 12 having said arm, whereby the several arms ll. on the shaft 12 will he rocked every time the handle 38 is moved. aiors 3 interlocked with the arms 11 will he 'correspondiugly actuated during the move ment of the arms 11.

Assuming that it is desired to ascertain how many units of different denominations of money are required to make up the value of a predetermined amount, and it being understood that for each denomination of money there is provided at least one of the actuators 3 and a corresponding counting device comprising a set of counting Wheels 213, the operator will set up the amount of money or item on the keyboard of the adding section A in the usual Way. This thus raising the arm 54 and ,7

Those of the actu- 'ment of the type carriers 95 is done by depressing the keys 29 which when set will control the ditiferential movement of the adding racks 80 that are adapted to be unlocked owing-to the shifting of certain locking bars 88, one of which is operable by the keys of each row. The differential moveis also, of course, controlled by the setting of the keys 29. Certain of thosclectors will be de pressed by the keys by which the amount is set up on the kcyboard and these par ticnlar selectors are thus moved downwards so th'a'f'thcir hooks 48 engage over the bail 41-7. The handle 38 is now pulled forwards and first effect isto actuate the bail l pulling the depressed selectors 20 longitudinally and causing these selectors to move the lector 20, its actuator ,counting device will be actuators 3 with which they are connected into interlocking engagement with the c0rrespending arms 11 of the. actuating shaft 12. The shaft 12 is not immediately rocked by the forward movement of the handle 38 because of the play of the stud 66 in the hook 64; (see Figure 14), but just as soon asihe. selectors 20 have been pulled longitudinally in the manner indicated, setting their actuators 3 properly, the hook 634 acts on the arm 63 to rock the said arm and the shaft 12, the several arms ll of the latter mean- While interlocked with actuators 33, causing said actuatorsto move outwards longitudinally to impart movement to the slides 208 ofpredeterrnined counting devices. It the amount to be set up on the machine is twenty-five dollars and fifteen cents, for instance, the key 29' designated 2 in the w, fourth row from the right (Figure 1) will be depressed, as will designated 5, 1 and 5 and first rows respectively. ,cThere is atleast one counting device for pennies, one for niclccls, one for dimes, one for quarters, and so on up with respect to the larger denomi nations of money. So, the depression of the also be the keys 29,

key 29 designated 2 of the fourth'row, above mentioned, will control-the twenty dollar sc- 3 and the associated given one increment ofin'ovement when the handle 38 is operated. In likcmanner the counting devices for the five dollar selector 20 and its actuator 3,

the ten centselector 20 and'its actuator 3,

" and the five cent selector 20 and its actuator 3, will he each given one increment of m0vcment on the operation of the handle 38. The respective counting devices or registers above referred to will he sctwith the numher 1 of unit Wheels 213 exposed, atthe conclusion of a transaction setting up the amount 'mentioned.

If a transaction to the amount of ninety cents be the tens press one of the selectors 20 having four of the third, second and ti] us indicating the 1 will be actuated to set the merit of movement.

both of the actuators f coun tors may be actuated to up two cents set up on the machine, incidental} to the depression of the key indicated 9 of row of keys 29, said key willdo projections 21'. Such selector 20 is interlocked by the depression of the key with the selector sails? and, on the initial pull. on the handle 38 the selector 20 is moved longitudi nally toward the right end of the machine and itsiour projections 21 shift four of the bails 22. The particular bails 22 which arethus actuated shift four actuators 3 into interlocking connection with the arms 1]. of the actuator shaft- 12 The said four actuators cooperate with the counters or registers fc'ri fifty cent pieces, twenty-five cent pieces, dimes and nic-kcls, and the final. operat on causes such actuation of the actuatojrs 8 that the fifty cent counter, twentyfive cent counter, dime counter and nickel counter are each given one increment of movement, thereby registering up the several denominations of money that will be required to make up the transaction of ninety cents.

Will is in Figure 9 the slide 2E8 is shown to ave it single lug 20?, the corresponding slide shown in Figure 10 is formed with two of these lugs. Thc object of this is'to permit of the employment of two of the actuators 3 one alongsidc the otheu, one capable 0t" engaging the innermost lug ,of the construction in Figure 10 whereby two increments oi movement may he imparted to the slide 208, or the actuator engaging the outermost lug capable of imparting only n single in cremen'b, of movement to the slide. Of course the movement of the units counting wheel 213 corresponds to the amount of movement imparted to crating therewith. Thus if the amount set up in the machine be forty dollars it is poss iblc by having an extra actuator 3 for the twenty dollar counter, to adjust the latter to 'ivu two increments of IIlGVQli'lPflt to the slice i208, setting the counter accordingly two twci'iiy dollar bills or twenty dollar gold pieces from the 'denominationalizing standpoint are news sary to make up the amount of the transaction sat up in the machine. lVh ilc at least one cuunter provided forcuch dcnomiuation 0 f currency of the particiila monetary system in connectionwith which the nun chine is used, as matter of tannin i'ci'eromm to United States nmney lt-WOllltljlK, pref erahlo to provide two counting devices for the counting of pennies, and two counting devices for the counting of dimes. When one cant is set up on the machine one ol the actuators 3 'for one oi the penny coi'mlcra crn ntor. one incrclftwo cents he set up 23 elf-one (if-the penny.

by the two increments of movement of the unihscounting wheel. If three cents to he satin :p the two actuators of one or" the counters, and one actuator of the other counter the slide 208 coopx for the pennies, may be rendered operable to correspondingly the counters on the movement or the handle Disabling means for counting mechanism.

Under certain conditions when it is not necessary to employ the counting mechanism of the countingsection B, that is, tor

. instance, when the adding section A is bemg used as an ordinary adding machine, it. is desirable that'opcration of the counters be discontinued. This is readily effected by the provision, as seen in Figuresli? and 13, of a no count key 31. that is adapted to be depressed and hold depressed by a notch (31 therein engaging the top plate of the keyboard of section A. C'Vhen key 61 is depressed against the tension of the spring 62 the lower end of the key has an olistancb ing pin 60 which engages a lever 58 pivoted to the frame of the machine. The lever 58 is adapted to move an arm 58 fixed on its axis 58 and the arm 58' is adapted to abut with the hook 64 and force the latter downwardly a ainst the action of a spring 65, holding t e hook disengage-d from the stud 66 so long as the key 61 remains down. Under these conditions it is obvious that in the transactions of the accumulating instrumentalities since the hook 64 is in this way maintained out of engagement with the stud 66 the movement of the handle 38 even though it rocks the arm 56, will not be trans mitted to the arm 63 and the shaft 12 will be maintained stationary during the accumulating, recording and other operations of the adding machine, and until the parts are restored to the normal positions shown in full lines in Figure 1d by a release of the key 61.

Having in View the foregoing it will be apparent that the machine hereinbefore described is a combined adding and counting machine, or the same maybe used solely as an adding machine in all of the advantageous ways in which the latter machines are commonly employed.

As seen in the drawings, the counting wheels 213 of each counting device are held in fairly close frictional contact by means of spring plates or spiders 234 one of which is carried on the shaft 212 for each set of counting wheels. Thus while the wheels 218 are free to rotate independently of one another there is sufficient friction between the wheels and the shaft 212 to cause these parts to be rotated together when the shalt is unlocked and turned by means of the handle or knob 233 for the purpose of zcroizing the wheels of the counting devices by engaging the projections or stops 231 with the resetting plate 230.
